Issues And Trends In Healthcare Delivery System

5.9K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Computed Tomography

6.3K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

148
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Imaging Studies I: CT and MRI

451
Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Imaging Studies for Cardiovascular System III: X-Ray

299
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Summary
This summary is machine-generated.

Telemedicine visits show lower diagnostic imaging use compared to in-person visits. This suggests telemedicine may not drive increased imaging, warranting further study on appropriateness.

Area of Science:

  • Health Services Research
  • Radiology
  • Digital Health

Background:

  • The COVID-19 pandemic accelerated telemedicine adoption.
  • Impact of telemedicine on diagnostic imaging utilization remains unclear.

Purpose of the Study:

  • To evaluate differences in diagnostic imaging utilization following telemedicine versus in-person visits.
  • Assess national-level trends in imaging after virtual and in-person consultations.

Main Methods:

  • Retrospective case-control study using de-identified national insurance data (2021).
  • Matched telemedicine and in-person visits.
  • Weighted multivariate linear models to compare post-visit imaging rates and counts within 7, 14, and 30 days.

Main Results:

  • Telemedicine visits had a 2.4 pp lower 7-day imaging utilization rate (29.7% relative decrease) compared to in-person visits.
  • This lower utilization trend persisted at 14 and 30 days.
  • A slight increase in the number of imaging studies (0.02, 1.5% relative difference) was observed for telemedicine visits with post-visit imaging.

Conclusions:

  • Telemedicine is associated with reduced diagnostic imaging utilization compared to in-person visits.
  • Telemedicine may not be a significant driver of increased imaging growth.
  • Further research is needed to assess the appropriateness of imaging ordered during telemedicine encounters.
